请教一下 ，thymeleaf 在 each 中无法区分是调用 JAVA 静态方法还是解析参数怎么解决？

代码如下：

<div class="container" th:each="article,articleState : ${list}">  
  <div class="col-lg-12">  
    <div class="card">  
      <div class="card-body d-flex flex-column">  
        <h4><a th:href="${article.articlePermalink}" th:text="${article.articleTitle}"></a></h4>  
        <div class="text-muted" th:text="${article.articleSummary}"></div> 
        <div class="d-flex align-items-center pt-5 mt-auto">  
          <div class="avatar avatar-md mr-3" th:style="'background-image: url('+${article.author.userAvatarUrl}+')'"></div>  
          <div> 
            <a th:href="${article.author.userUrl}" class="text-default" th:text="${article.author.userName}" ></a>  
            <small class="d-block text-muted" th:text="${com.voally.vertical.util.Utils.idBuilder()}"></small>  
          </div> 
          <div class="ml-auto text-muted">  
            <a href="javascript:void(0)" class="icon d-none d-md-inline-block ml-3"><i class="fe fe-heart mr-1"></i></a>  
          </div> 
         </div> 
        </div> 
      </div> 
    </div>
</div>
​

错误信息：

org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "com.voally.vertical.util.Utils.idBuilder()" (template: "index" - line 161, col 83)
